This invcntionrelatesto head lights, part1 hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

This head lamp comprises generally, a"

body having front and rear sections and an intermediate transverse portion, the front section having a lightprojecting opening and the rear section preferably having a reflector and also having a wire passage in the rear of the reflector, a lamp located in the body and arranged to project light laterally through the transparent portion as well as I01 its object, a particularly simple, eco- Theinvention consists in the novel features and in the combinations and constructions" 1929.

interposed between the front and rear sec tions of the body and between connecting pillars-between the front and rear sectlons.

4 is the reflector mounted in the rear section 1, the rear section 1 being shaped to c'onform to the reflector and being provided in I the rear of the reflector with a Wire passage 5. This wire passage extends vertically diametrically of therear section 1 and of the reflector and is open at its lower end at'6 to the outside of the rear section and at its upper end at ,7 through the front side of the 7 rear section at the upper edge-of the reflec-' tor 4.

The wire passage 5 is provided with a suitable internally threaded nipple 8 at its lower end for receiving-a conduit which encloses the service wires 9, 10 to the lamp. The rear section 1 is also provided with an annular flange 11 by means of which it is anchored in position to the vehicle or the dash thereof or to anyothersupport by means of screws ext-ending through openings 12 in said flange or in thiclienedlug-like portions 13. thereof. The reflector 4 is usually glass and suitable strips ofcushioning material lt are inter posed between therear side of thereflector and the rear wall of the rear section 1. The reflector is held in position in any suitable manner as by an annular ring 15 thrusting against the front edgevthereof and secured to the rear section 1 as by screws 16.

The frontsection 2 is usually in the form of a-ring and includes in addition to the body portion, an annular door frame 17lfor supporting a glass or a lens 18. Preferably, the door is hinged at 19 to the'ring 2 and is de tachably held in its closed'position by a connection between the door and the rear section 1. Ashere illustrated, the door isiprovidedj with hi-ngeleaves 20 which coact with complemental hinge leaves 21 on the ring or sec tion 2 and the hinge pin 19 extends through the leaves 20 and 21. The'door is held in its closed position by a hinged or swinging member connecting the free edge of the door to the rear s'ectionln This hinged member as here shown comprises atubular body portion 22 hinged at 23 to lugs on the rear section 1 or the flange 11 thereof, a plunger24 movable V in the tubular section 22 against the action y in riage 42.

of a spring 25, the plunger being provided with a head 26 at its front end for coacting with the walls of an open ended slot 27 formed in a lug 28 on the door 17.

The head 26 is provided with a suitable handle 29. By pulling outwardl y on the handle, the head 26 is moved away from the lug 28 and upon downward movement of the handle, the'plunger 24 is moved out of the slot 27 so that the door can be swung open. hen the door is closed, the reverse of these movements brings the head 26 into holding engagement with the door. Thus the door is hinged to the front section 2 and held in its closed position by connections between the door and the rear section 1. The front section or ring 2 is provided with a cylindrical flange 30 onthe front side thereof for coacting with a gasket 30 m an annular groove in the door frame 17.

Thelens 18 is held in position in any suitable manner as by detachable lugs 31, Figure 4, mounted on studs or screws 32 projecting inwardly from the door frame and nuts 34 threading on the studs or screws against the lugs. In the form shown in Figures 1 and 2, the sections 1, 2 are secured together as by clamping members on tie-bolts 35 extending through marginal lugs 36 on the section 2 and through the flange 11 of the section 1, the heads of these bolts being preferably located on the front side ofthe section 2 and the other end threading at 37 into the flange 11 of the rear section 1. These bolts are located outside of the transparent cylindrical wall 3. The opposing sides of the sections 1, 2 are provided with suitable grooves for receiving gaskets 38, 39 in which the rear and front edges of the transparent wall 3 are seated.

40 designates the lamp mounted in a suitable lamp socket 41 which is supported by a carriage 42, this carria e being in turn carried by a support mounted on either one of the front or rear se tions, preferably on the front section 2. As here illustrated, a bracket 43 is secured to the front section 2, this bracket projecting into the space enclosed by the transparent wall 3 and the bracket is provided with means for securement to the car- Thus, the lamp is supported entirely in front'of the reflector and is accessible for adjustment relatively to the focusof the reflector by opening the door. As here illustrated, the bracket is provided with verticalguid-e rods 44 along which. the carriage 42 is adjustable, the carriage being held in its adjusted position by screws 45., The wires 9, 10 extend from the opening 7 to the lamp socket terminal. v

As shown in Figures 6 and 7, the rear section is provided with projections or posts 46 usually integral therewith and these projections extend toward the front section and the front section is secured to the ends thereof as by screws 47. The transparent portion of the lamp body is formedin a plurality of sections which are interposed between the front and rear sections and also between the posts 46, the posts being formed with grooves or rabbets 48 in which the ends of the sections 3 are seated. These posts 46 preferably taper slightly from their base toward their outer ends as shown at 49, Figure 6. I

In the form shown in Figures-6 and 7, the

lamp projects, axially through the reflector 50 and the lamp. socket 51 is mounted'on a carrier 52 in the rear portion 53 of the rear section 54 of the body, the carrier shown in Figure 7 being similar to that shown in Figure 2. The reflector 50 is also glass and is seated at its margins against cushions 55 in terposed between the margins of the reflector and an annular bearing surface 56 on the section 54. i 1

This head light is particularly advantageous in that it is simple and economical in construction, easily assembled and provides in a particularly simple and eflicient manner for the lateral projection of the light across the front of the vehicle.

What I claim is:

1. A head light construction comprising a concave rear portion having an annular flangeextending from its outer edge, a front portionhaving an annular flange complemental to the flange on the rear portion, a cylindrical,ftransparent, intermediate member between said flanges, means for securing the sections together and thereby holding the transparent member in position, a reflector located Within the concave rear portion, a door hinged to the front portion and carrying a projecting lens, a light support carried by the front portion for locating a light source in the focal axis of the reflector.

2. A head light construction comprising a concave rear portion having an annular flange extending from its outer edge, a front portion having an annular flange complemental' to the flange on the rear portion, a cylindrical, transparent intermediate member between said flanges, means for securing the sections. together and thereby holding the transparent member in position, a reflector lo- FRANK BUCHANAN,
